Question

I’ve just released my first app to the app store.

I’ve been developing the app with Xcode 4.0.2 with iOS 4.2.1 devices. Because my device is a 2nd gen iPod Touch I can’t get iOS 5 on it so I can’t use Xcode 4.1 with it which also means I can’t build to iOS 5 devices with my version of Xcode.

My friend who has a 3GS running iOS 5 has just downloaded the app, and one specific section of it crashes when tapped (aaaah!) – it works fine for me.

I’ve just looked at his crash logs and they just show EXC_CRASH(SIGBART) – with nothing that can really help me determine the cause of the error.

I considered building to his device to get the runtime crash log (which shows an actual code-level exception), but I realised I can’t because I’m using Xcode 4.0.2.

I can’t upgrade my Xcode version because then I won’t be able to test on devices myself!

What can I do?

Answer 1

The current Xcode version is 4.2 which does support debugging on devices with iOS 4.2.1 as I use an old iPhone 3G with 4.2.1 for debugging.

In Xcode 4.2 there is also a new section in the preferences window that says “Downloads”. From that tab you can download additional packages, one of them is support for debugging with even older iOS devices.
